Analyzing Fluid-solid Coupling of Bioprosthetic Heart Valve with PISO Algorithm

  • 摘要: 应用任意拉格朗日欧拉法推导了生物瓣膜与血液的耦合方程,并借助压力隐式算子分割算法对血液的动量方程进行离散,得到耦合过程的速度迭代方程。根据Fluent中的压力隐式算子分割算法PISO (Pressure implicit with splitting of operators)对生物瓣膜模型进行动态力学分析,得到了生物瓣膜的变形情况。仿真分析结果显示生物瓣膜的变形主要发生在每片瓣叶的自由边,而腹部的变形较小,而且在瓣膜打开的过程中自由边会出现卷曲。对生物瓣膜使用同样的环境进行脉动流实验模拟,得到了相同的结果。仿真和实验结果证明,该方法可以用在生物瓣膜的流固耦合分析中,同时也为生物瓣膜的进一步优化提供了参考。
